How? Explain it.

Stress = force/area.
According to this, if we increase the stress so the area of section is decreased. So when stress is equal to working stress so the area becomes infinite.

Freely prismatic bar stress is equal zero. So area is infinite.

Consider S = stress.
Then partial derivative of stress with respect area.
dS/dA=pd(A power minus 1)/dA,
solve it,
A=p/0,
A= infinite.
